Abstract

L'invention concerne un procédé et un appareil de détermination d'une matrice de précodage. L'invention peut déterminer un premier niveau d'une matrice de précodage sur la base d'informations d'indication relatives à une matrice spatiale retournée par un terminal, de sorte à réaliser un précodage tridimensionnel selon un état de canal et améliorer la capacité d'un canal. Le procédé comprend les étapes suivantes : une station de base envoie une pluralité de groupes de premiers signaux de référence, la pluralité de groupes de premiers signaux de référence étant en correspondance biunivoque avec une pluralité de dimensions d'un réseau d'antennes, chaque groupe de premiers signaux de référence de la pluralité de groupes de premiers signaux de référence étant utilisé par le terminal pour estimer des informations relatives à une matrice spatiale sur une dimension correspondante ; recevoir les informations relatives à la matrice spatiale, retournées sur la base de la pluralité de groupes de premiers signaux de référence ; et, d'après les informations relatives à la matrice spatiale, déterminer le premier niveau de la matrice de précodage.
